Development in reading and math in children from different SES backgrounds: the moderating role of child temperament

Socioeconomic risks (SES risks) are robust risk factors influencing children's academic development. However, it is unclear whether the effects of SES on academic development operate universally in all children equally or whether they vary differentially in children with particular characteristics. The current study aimed to explore children's temperament as protective or risk factors that potentially moderate the associations between SES risks and academic development. Specifically, latent growth modeling (LGM) was used in two longitudinal datasets with a total of 2236 children to examine how family SES risks and children's temperament interactively predicted the development of reading and math from middle childhood to early adolescence. Results showed that low negative affect, high effortful control, and low surgency mitigated the negative associations between SES risks and both reading and math development in this developmental period. These findings underline the heterogeneous nature of the negative associations between SES risks and academic development and highlight the importance of the interplay between biological and social factors on individual differences in development.     

Effect of interaction type on the characteristics of pet-directed speech in female dog owners

Recent studies focusing on the interspecific communicative interactions between humans and dogs show that owners use a special speech register when addressing their dog. This register, called pet-directed speech (PDS), has prosodic and syntactic features similar to that of infant-directed speech (IDS). While IDS prosody is known to vary according to the context of the communication with babies, we still know little about the way owners adjust acoustic and verbal PDS features according to the type of interaction with their dog. The aim of the study was therefore to explore whether the characteristics of women’s speech depend on the nature of interaction with their dog. We recorded 34 adult women interacting with their dog in four conditions: before a brief separation, after reuniting, during play and while giving commands. Our results show that before separation women used a low pitch, few modulations, high intensity variations and very few affective sentences. In contrast, the reunion interactions were characterized by a very high pitch, few imperatives and a high frequency of affectionate nicknames. During play, women used mainly questions and attention-getting devices. Finally when commanding, women mainly used imperatives as well as attention-getting devices. Thus, like mothers using IDS, female owners adapt the verbal as well as the non-verbal characteristics of their PDS to the nature of the interaction with their dog, suggesting that the intended function of these vocal utterances remains to provide dogs with information about their intentions and emotions.     

Lived Experiences of Men With Dissociative Identity Disorder

Dissociative disorders affect 29% of the clinical population, with women diagnosed 9 times more often than men. For this study, the authors used a phenomenological approach to uncover experiences of 5 men with dissociative identity disorder. Findings revealed 5 themes: history, alters, male gender expectations and identity, challenges, and strengths and support. Implications for practitioners are discussed.     

Online psychophysics: reaction time effects in cognitive experiments

Using the Internet to acquire behavioral data is currently on the rise. However, very basic questions regarding the feasibility of online psychophysics are still open. Here, we aimed to replicate five well-known paradigms in experimental psychology (Stroop, Flanker, visual search, masked priming, attentional blink) in three settings (classical “lab”, “web-in-lab”, “web”) to account for possible changes in technology and environment. Lab and web-in-lab data were both acquired in an in-lab setting with lab using “Gold Standard” methods, while web-in-lab used web technology. This allowed for a direct comparison of potential differences in acquisition software. To account for additional environmental differences, the web technology experiments were published online to participate from home (setting web), thereby keeping the software and experimental design identical and only changing the environmental setting. Our main results are: First, we found an expected fixed additive timing offset when using web technology (M = 37 ms, SD = 8.14) and recording online (M = 87 ms, SD = 16.04) in comparison to lab data. Second, all task-specific effects were reproduced except for the priming paradigm, which couldn’t be replicated in any setting. Third, there were no differences in error rates, which are independent of the timing offset. This finding further supports the assumption of data equality over all settings. Fourth, we found that browser type might be influencing absolute reaction times. Together, these results contribute to the slowly but steadily growing literature that online psychophysics is a suitable complement – or even substitute – to lab data acquisition.     

The benefits of self-forgiveness on mental health: Evidence from correlational and experimental research

Previous research on self-forgiveness is mixed. Some argue self-forgiveness may have a salutary influence on mental health problems following an offense, whereas others suggest it may provide an excuse to reoffend. In two studies, we provide correlational and experimental evidence for the salutary effects of self-forgiveness following an offense. In Study 1 (N = 100), self-forgiveness was associated with lower levels of disordered eating behavior. In Study 2 (N = 462), participants recalled a drinking-related transgression, and were randomly assigned to a self-forgiveness or neutral priming condition. Results revealed that participants in the self-forgiveness condition reported significantly more self-forgiving beliefs and fewer feelings of remorse and self-condemnation than participants in the neutral priming condition to the degree that participants believed their drinking was the cause of the offense. These findings highlight the salutary effects of self-forgiveness.     

Temporal precision and the capacity of auditory–verbal short-term memory

The capacity of serially ordered auditory–verbal short-term memory (AVSTM) is sensitive to the timing of the material to be stored, and both temporal processing and AVSTM capacity are implicated in the development of language. We developed a novel “rehearsal-probe” task to investigate the relationship between temporal precision and the capacity to remember serial order. Participants listened to a sub-span sequence of spoken digits and silently rehearsed the items and their timing during an unfilled retention interval. After an unpredictable delay, a tone prompted report of the item being rehearsed at that moment. An initial experiment showed cyclic distributions of item responses over time, with peaks preserving serial order and broad, overlapping tails. The spread of the response distributions increased with additional memory load and correlated negatively with participants’ auditory digit spans. A second study replicated the negative correlation and demonstrated its specificity to AVSTM by controlling for differences in visuo-spatial STM and nonverbal IQ. The results are consistent with the idea that a common resource underpins both the temporal precision and capacity of AVSTM. The rehearsal-probe task may provide a valuable tool for investigating links between temporal processing and AVSTM capacity in the context of speech and language abilities.

Students’ Oppositional Behaviors and Engagement in School: The Differential Role of the Student-Teacher Relationship

Students presenting oppositional behaviors often display lower behavioral and emotional engagement in class as compared to their peers. Moreover, children in general are known to be deeply affected by their relationships with teachers while in school. It is therefore possible that such relationships could also influence the engagement of students presenting higher levels of oppositional behavior. As a way of verifying this hypothesis, the present study investigated the contribution of students’ levels of oppositional behavior to their behavioral and emotional engagement in literacy. Furthermore, it examined whether these relationships were different for boys and girls, or changed as a function of two components of student-teacher relationships: closeness and conflict. Three hundred and eighty five third and fourth grade students and their teachers participated in the study. Two series of linear regressions were conducted. Findings indicate that students who presented higher levels of oppositional behavior showed lower behavioral engagement than their peers. Moreover, students who had close relationships with their teachers reported higher behavioral engagement. Although closeness in student-teacher relationships protected students from behavioral disengagement, students with higher oppositional behaviors were less protected than students who presented lower levels of oppositional difficulty. Having a warm relationship with a teacher was also more beneficial for the behavioral engagement of girls, whereas a high level of conflict between student and teacher was more harmful for the emotional engagement of boys. This was deemed to be true whether the boys or girls presented high levels of oppositional behavior or not. Overall, our findings highlight the importance of the student-teacher relationship in fostering all students’ engagement in school.
